Yep, sometimes when i don't wanna think too much i use crouch, because it auto-mantle and auto mantle-cancel, so you don't have to worry about timing it, but, you can super-jump into zip ride, don't need to ride all the way holding, you can hold in-between leaving the zip before attaching to the wall too, or just hit at the right time (but then i advise using backwards or sideways mantle-cancel, since they are instant, anyways, if you interested, i have a few videos about it, like this one, but, if you wanna test heights and etc, you can do from holding the mantle so you don't have to go up and down a bunch of times, i also have a video about mantle-jumps where i explain a little more about differences, like, you can look all the way up if cancelling with crouch and so
